👋 Hi, Welcome to the Crypto and System Security (CryptoSys or CSS) Lab at Nankai Univeristy, directed by Prof. Ding Wang. Our research interests include:
(1) Machine learning-based techniques for authentication.
(2) Protocols, including Password-based, Blockchain-based, Lattice-based ones;
(3) Multi-factor authentication, including passwords. devices, biometrics and others;
We have open-sourced several projects related to our published research, aiming to contribute to both academia and industry.
Feel free to explore! 👀
